For modelling hybrid systems, we have extended Event B based on its framework with the differential event. The differential event describes continuous behaviors of hybrid systems by differential equations and evolution constraint, whose proof obligations provide dynamical properties of a model. In order to ensure the safety and reliability of a model, proof obligations should be proved. It is difficult...
In this paper, we present a new spectrum-hole prediction model for cognitive radio (CR) systems based on the IEEE 802.11 wireless local areas networks. We have also analyzed the distribution of interval between two consecutive packets (ITCP) based on a simple two-user network. For multiuser networks, we have investigated the distribution of ITCP and study its characteristics using Bayesian inference...
In this paper, we introduce an open source toolbox named Flexibot for modeling and simulation of flexible manipulators. Flexibot is based on open-sourced scientific computation and simulation software Scilab/Scicos and Modelica. The whole toolbox consists of symbolic derivation, parameter computation, and block generation as well as simulation module. Users are not only able to use our presented block...
A Mesic respiratory system parameter identification is studied in this paper for providing the useful theory and data support in the improvement of human respiratory model accuracy, respiratory disease diagnosis and design of the new ventilator. The Mesic respiratory system model is established based on Simulink platform. The least-square algorithm is then used to do the static and dynamic parameter...
This paper proposes a method to combine the digital images and Laser point clouds to reconstruct the 3D model of the archaic glockenspiel. All the stations of the Laser point clouds are connected according to the ICP arithmetic. Then image matching is used to register the high resolution digital images and the Laser synchronous images to gain the corresponding texture of the Laser point clouds. Finally,...
